Aim for the lungs or heart to get a bonus reward at the end of a level. Lung shots are worth $25 and heart shots are worth $50. This is done easier with the help of the Infrared enhancement to your rifle scope which shows you exactly where the lungs and heart are located when zoomed in. Shoot the body parts marked in red on single target dinosaurs to make it flinch and allow you more time to reload and check your position. This is very important while hunting large dinosaurs such as Tyrannosaurus Rex. To take down predators efficiently, wait until they leap on you to get a clear shot on their heart, lungs, or brain. Make sure you can defend yourself if there are several of them around. When hunting herbivores, carefully aim your first shot. Most herbivores, with the exception of Triceratops and Stegosaurus, will flee quickly when injured. Use the assault rifle to take down small and fast-moving omnivores. It is more important to have a weapon that can quickly pump out rounds at the fast moving targets instead of relying on power and zoom.
